Is there any specific procedure to follow when insulating bearings? If so, what is it?

Following are some guidelines to follow when insulating bearings:

Apply sufficient alumina oxide coating to allow for finished grinding to original bearing journal

dimensions with a 63 RMS, or better, surface finish.  A phenolic sealer must be applied after the

initial machining, but before the finish grind.

Suggested insulation materials:

*       Alumina oxide (Metaceram® 25010 or equivalent) - P/N 936521.

*       Bonding material (Metaceram® 21021 or equivalent) - P/N 936520

*      Sealer (Metcoseal® AP from “Metco”) - P/N  936557.
